On-Vehicle Inspection [11/2021 - ]: Procedure
- INSPECT VACUUM SENSOR ASSEMBLY
- Turn the ignition switch to ON.
- Read the air pressure value from the Data List.
Powertrain > Engine > Data List
Tester Display PCV 1 Pressure HINT:
- Standard atmospheric pressure is approximately 101 kPa (abs) (15 psi (abs)).
- For every 100 m (328 ft) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies by weather.
- Using a vacuum pump, set the vacuum sensor assembly.
- Using a vacuum pump, read the value when pressure is applied and when pressure is decreased.
OK
The pressure values when applying pressure or decreasing pressure using the vacuum pump and the Data List values are nearly the same.
NOTE:- Do not apply a pressure of 50 kPa (0.5 kgf/cm2 , 7.3 psi) or more to the vacuum sensor assembly.
- Do not apply a vacuum of 50 kPa (375 mmHg, 14.8 in.Hg) or more to the vacuum sensor assembly.
HINT:
The pressure value displayed in the Data List is the pressure value indicated on the vacuum pump with the air pressure value added.
EXAMPLE:Vacuum Pump Pressure Value Air Pressure Value Equation Data List Value When vacuum is applied at 30 kPa (225 mmHg, 8.86 in.Hg) 100 kPa (1.0 kgf/cm2 , 15 psi) -30 + 100 = 70 70 kPa (0.7 kgf/cm2 , 10.2 psi) When pressure is applied at 20 kPa (0.2 kgf/cm2 , 2.9 psi) 20 + 100 = 120 120 kPa (1.2 kgf/cm2 , 17 psi)
